Question

\(0,36.\dfrac{-5}{9}\) 

\(\dfrac{-7}{6}:1\dfrac{5}{7}\)

Answer 1

\(-0,36\cdot\dfrac{-5}{9}\)

\(=-\dfrac{9}{25}\cdot\dfrac{-5}{9}\)

\(=\dfrac{5}{25}\)

\(=\dfrac{1}{5}\)

_____

\(\dfrac{-7}{6}:1\dfrac{5}{7}\)

\(=-\dfrac{7}{6}:\dfrac{12}{7}\)

\(=-\dfrac{12}{6}\)

\(=-2\)

Answer 2

a) \(0,36\cdot\dfrac{-5}{9}\)

⇔ \(\dfrac{9}{25}\cdot\dfrac{-5}{9}\)

⇔ \(-\dfrac{1}{5}\)

b) \(-\dfrac{7}{6}\div1\dfrac{5}{7}\)

⇔ \(-\dfrac{7}{6}\div\dfrac{12}{7}\)

⇔ \(-\dfrac{7}{6}\cdot\dfrac{7}{12}\)

⇔ \(-\dfrac{49}{72}\)
